%X Severe burns lead to metabolic changes, systemic inflammatory response syndrome, and multiple organ dysfunction syndrome. Omege-3 polyunsaturated fatty acids (PUFAs) have anti-inflammatory properties. In the absence of substantial evidence for use on major burns, we systematically reviewed the efficacy of omega-3 PUFAs for patients with severe burns.
We comprehensively searched MEDLINE, Web of Science, Embase, Cochrane Library, China National Knowledge Internet, Wang Fang Data, Chinese Biomedicine Database, and Science Direct databases to collect randomised controlled trials of omega-3 PUFAs administered to patients with burns from January 2000 to June 2023. Two researchers independently screened the literatures, extracted the data, and assessed the risk of bias in the included studies. The outcomes were mortality, the risk of severe sepsis, septic shock, and multiple organ dysfunction syndrome. Data synthesis was conducted using Review Manager. Trial sequential analyses (TSA) for outcomes were performed.
Three randomised controlled trials involving 140 patients were included. Of these, 71 patients received omega-3 PUFAs. The results showed that omega-3 PUFAs significantly reduced the incidence of severe sepsis, septic shock, multiple organ dysfunction syndrome (RR = 0.38, 95 % CI [0.19, 0.75], P = 0.005), C-reactive protein levels (MD = -39.70[-81.63, 2.23], P = 0.06), and improved respiratory outcomes. However, there was no difference in 14-day mortality (RR = 1.10, 95%CI [0.59, 2.05], P = 0.75). TSA showed that the results for the incidence of severe sepsis, septic shock, multiple organ dysfunction syndrome are insufficient and inconclusive.
Omega-3 PUFAs may reduce inflammatory response and risk of sepsis, septic shock, and multiple organ dysfunction syndrome in severe burns patients and may shorten hospital stay but cannot reduce risk of death. Due to the limitation of the quantity and quality of the included studies, the evidence level is low, and the conclusions need to be verified by larger scale and higher quality randomised controlled trials.
